摘要：
The WO3/TiO2 nanocomposites were successfully prepared via a facile oxalic acid assisted hydrothermal process. The oxalic acid played a vital role on the preparation of WO3/TiO2 nanocomposites. Notably, it has been observed that the nanocomposites exhibited the wider absorption edge, and the higher photocatalytic activity, compared with pure TiO2. In addition, the photocatalytic mechanism was proposed, and it elaborated that WO3/TiO2 nanocomposite promoted the separation of the photoproduction carriers, and improved photocatalytic activity. The WO3/TiO2 nanocomposite may have a potential application as a UV–visible photocatalyst.
